March weather forecast
Honiara, Solomon Islands

The climatic conditions in Honiara in March echo those of February, with similar high temperatures. However, the amount of rainfall received increases, marking a contrast in the weather pattern with a recorded rainfall of 299mm (11.77"). The sea temperature experiences a slight increase, making beach expeditions all the more enjoyable. Though the increase in rain may cause some disruption to outdoor plans, the warm temperatures soften the intensity of the wet days. The relative humidity remains high, making the environment moist and warm.

Temperature

The shift into March reveals an average high-temperature of a still warm 28.8°C (83.8°F), closely mirroring February's climate. Honiara's March nights demonstrate minimal variation from the daytime temperatures, with an average of 23.8°C (74.8°F).

Heat index

During March, the heat index is evaluated at a torrid 35°C (95°F). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.
Remember that heat index calculations are made for conditions in the shade with light wind. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a metric representing the sensation of warmth when air temperature and moisture come together. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.

Sustain precautions and conform to sun safety norms. Preventing sunburn is necessary. The Sun emits the most powerful UV radiation between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration. Notice! The Sun's UV exposure elevates with sand and water reflections.
